The invention discloses an illumination projection lens and an illumination projection lens module. The illumination projection lens comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens which are sequentially arranged from an image side to an object side along an optical axis, the second lens has negative focal power; the image side surface of the third lens close to the optical axis is a convex surface; the fourth lens has positive focal power; a fifth lens element having a convex image-side surface near the optical axis; the object side surface of the sixth lens is a concave surface close to the optical axis; the illumination projection lens satisfies the following conditional expressions: 7lt; (TTL/f)/Tan (Semi-Fov) lt; 10; 1lt; the TTL/max Clear Diult is used as a template; 1.5 parts; wherein TTL is the optical total length of the illumination projection lens; the Semi-Fov is a half field angle of the illumination projection lens; f is the effective focal length of the illumination projection lens; and the max Clera Dia is the maximum effective light aperture of the illumination projection lens.
本发明公开了一种照明投影镜头以及照明投影镜头模组,包括沿着光轴由像侧至物侧依序排列的:具有正光焦度的第一透镜;具有负光焦度的第二透镜;第三透镜,其像侧面在靠近光轴处为凸面;具有正光焦度的第四透镜;第五透镜,其像侧面在靠近光轴处为凸面;第六透镜,其物侧面在靠近光轴处为凹面;照明投影镜头满足以下条件式:7<(TTL/f)/Tan(Semi‑Fov)<10;1<1.5;其中,TTL为照明投影镜头的光学总长;Semi‑Fov为照明投影镜头的半视场角;f为照明投影镜头的有效焦距;max Clera Dia为照明投影镜头的最大有效光线口径。
